Biological Safety Cabinet HR1200-IIA2

Patent Intelligent Constant Air Velocity

The professional hot-bulb air velocity transducer performs real-time monitoring on the air velocity of the working area，compares it with the standard air veloctiy，and keeps the safety cabinet under constant air velocity through adjustment of the fan speed by microcomputer system

Professional Air-flow Distribution Module

Through professional air flow distribution design，the air flow of the worktable is more uniform，with the noise＜62dBA

LNS Green Energy-saving Mode

When the human body detecting module detects under the intelligent mode that the person is outside the operating area for 15 minutes，the microcomputer program will automatically switch the cabinet to LNS green energy conservation mode，so as to realize noise reduction and energy conservation and to improve the service life of the filter

Ultra Low Penetration Air Filter System

Camfil （ULPA）filter are tested to a typical efficiency of ＞99.999% for 0.12 micron particles. ULPA Filter provides vertical laminar flow to the workable，so as to protect samples from pollution.

304 Stainless Steel Operation Platform & Internal Wall

• Stainless steel operation platform without screws, no accumulation of contaminant
• Dismountable air in-flow plate, easy to clean and disinfect
• Internal wall is constructed by a single plate, and the 12mm arc angle conner leaves no cleaning blind area
• The volume of liquid tank is over 4L, equipped with outlet valve for convenient cleaning and maintaining
• Concaved operation platform, waste liquid easily collected
• Adjustable supporter (0-75mm) without exposed screw thread, preventing the germs from multiplying

Ultra Low Penetration Air Filtration System

• American AAF brand ULPA filter
• Tested to a typical efficiency of 99.9995% for 0.12micron particles
• Provides FED STD 209E class 1 (or ISO14644.1 class 3) clean air to work surface in a stable vertical laminar flow to protect samples
• The exhaust ULPA filter traps biohazard particles acquired from the work surface before air is exhausted to the room, offering personnel and environmental protection

High Efficiency Blower System

• The blower system is designed for high performance operation, maximum energy efficiency and minimal maintenance
• Self cooling system reduces energy consumption while enhancing reliability

Digital Microprocessor Control System

• Sound & light alarming function
• UV sterilization reservation setting function
• Time setting function

Ergonomic Design

• The 10° angled viewing window improves comport and alleviates fatigue of operator
• 75mm adjustable supporter ensures correct height for different users
• UV sterilization reservation function
• Lamp is set behind supporter, making eyes more comfortable
• Automatically remind when filter lifetime less than 10% , so that filter can be changed in time
• Removable stainless steel work surface makes convenient cleaning
• Draining valve is easy to clean and maintain

Interlock Safety Protection

• Glass sash and the blower/motor interlocking
• Fluorescent light & UV light 
• UV light, blower/motor and fluorescent light interlocking
• Sash and fluorescent light interlocking

Intelligence Alarm System

• Alarm when opening height of sash exceeds the safety limit line
• Alarm when airflow fluctuation exceeds 20%
• Alarm when sash is not closed properly but blower turned off
• Alarm when filter life is less than 10% of total lifetime
